LIQUID-SEPARATOR.

Specification of Letters Patent.

Patented Mar. 15, 1910.

To all whom it may concern:

Be it known that I, FRANCIS G. EPPLEY, a citizen of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in Liquid-Separators, of which the following, taken in connection with the drawings, is a description.

My invention has for its object the production of a machine for separating liquids of different specific gravities, and is designed in this instance to be used more particularly for separating cream from milk.

In the operation of the machine the liquid of the higher specific ravity will occupy the zone of high centrifugal force, and the liquid of the lower specific gravity will occupy the zone of lower centrifugal force. In the separation of the cream globules from the milk, it is necessary for the cream to move toward the inner portion of the centrifugal bowl. When the cream globules are grouped together and having only a small amount of milk mixed therewith, they will travel to the cream wall easier and quilcker than if they were mixed with the mi k.

Therefore one of the objects of this invention is to provide a separator having a plurality of wings which will separate the cream globules from the milk.

A further object of my invention is the novel form of wings or blades used, having perforations therethrough which facilitates the separation of the cream globules from the milk globules, the corrugated wings collecting the cream globules more rapidly, the perforations in the wings permitting the cream to pass rapidly through the machine and out into the receptacle. It

thereby increases the capacity of the ma chine by increasing the rapidity of the separation.

In the accompanying drawings forming part of this specification, and in which like letters of reference indicate corresponding parts, I have illustrated one form of device embodying the principal features of my invention, although the same may be carried into effect in other ways without in the least departing from the spirit thereof, and in these drawings Figure 1 is a vertical sectional view taken through the center of the machine; Fig. 2 is a top plan view with part of the cap broken away; Fig. 3 is a top plan view with the cap and disk removed showing the position of the wings when the separator is in operation; Fig. 4 is a transverse cross section; Fig. 5 is a detail of one of the corrugated wings; Fig. 6 is a sectional detail of the cap.

In carrying out my invention A represents a centrifugal separating bowl supported inside of the receptacle A. The separator bowl is rotatably mounted upon a spindle a. The lower end of the spindle a is provided with an angular opening a, into which is fitted an angular stud which is carried by the driving shaft (not here shown). Inside of the bowl A are a plurality of corrugated wings B supported in vertical position between the upper and lower disks 6, 6. These wings are pivotally secured at their inner edges to the rings Z2 6 thus when assembled, forming a circular series of wings, leaving a central opening 6 concentric with the bowl A. Each of the wings B is curved from the inner to the outer edge thereof on a line transverse of its length, as shown in Fig. 3. These wings are also provided with a plurality of corrugations, b following the aforesaid lines of curvature, and these corrugations are so arranged that when assembled the wings will nest together for insertion into the bowl A. Along the pivotal edge of each of the wings B and between each corrugation I have provided the apertures 6 the purpose of which will be hereinafter explained.

The upper disk I; is provided with a plurality of perforations 0, these perforations being arranged upon curved lines, extending from the center to the circumference of the disk as shown more particularly in Fig. 2. The liquid to be separated is passed through these perforations, there being one line of perforations for each one of the corrugated wings B. This disk is adapted to fit inside of the bowl A when the separator is ready for use.

C is a cover, cone-shaped at its base, with an u wardly extending neck having a circum erential flange 0 around the edge thereof. This cover is the same diameter at the base as the disk 6 and in position rests upon said disk inside of the bowl A. A feed tube 0 is made separately, or formed integrally, with the neck of the cover and extends 6. In a liquid separator, the combination of a stationary rece tacle, a rotatable separator bowl inside of said receptacle, a plurality of curved corrugated wings inside of said receptacle, said wings being vertically pivoted at a point between the center and the circumference of the bowl, the inner edges thereof having perforations and the outer edges contacting with the wall of the bowl, substantially as described.

7. In a liquid separator, a stationary receptacle, a revoluble separator bowl inside of said receptacle, a plurality of curved cor- 'rugated wings inside of said bowl, said wings being vertically connected in a circular series upon pivots transverse to the lines of curvature and so arranged that the corrugations of the wings will nest together inside of the bowl, and a cone-shaped cover having radially extending wings upon the under side thereof, substantially as described.

S. In a liquid separator, the combination of a stationary receptacle, a revoluble bowl inside thereof, perforated, corrugated wings pivotally mounted inside of said bowl along the vertical edge of the said wings, a perforated disk covering said wings and fitting inside of the bowl, a cover having a neck extending above and below the same, said neck having an opening extending vertically therethrough, and havmg openings through the walls thereof beneath the cover, the edges of the wall surrounding said last named openings being inwardly beveled on one side thereof and outwardly beveled on the other, substantially as described.

9. In a liquid separator, a revoluble separator bowl, a cover for said bowl, said cover having a neck extending above and below the same, said neck having an opening extending vertically therethrough, and having openings through the wall thereof beneath the cover, the edges of the wall surrounding said last named openings being inwardly beveled on one side thereof, and outwardly beveled on the other, and radial wings extending from said neck to the circumference of the cover, substantially as described.

10. In a liquid separator, a stationary receptacle, a revoluble separator bowl mounted upon a spindle inside of said receptacle, perforated, curved, corrugated wings pivotally secured around a circle inside of said bowl, a cover for said bowl, said cover being provided with a neck extending above and below the same, said neck having an opening extending vertically therethrough and having openings in the walls thereof beneath said cover, wings extending from the neck to the circumference of the cover, an elongated tube 011 one side of the neck, said tube extending into the central opening in the aforesaid bowl, substantially as described.

11. In a liquid separator, a stationary receptacle, a revoluble separator bowl mounted upon a spindle inside of said receptacle, perforated, curved, corrugated wings pivotally secured in a circular series concentric with said bowl, a cover having a neck ex tending above and below the same and having an opening therethrough, said neck also having openings in the walls thereof beneath the cover, the edges of the wall surrounding said last named openings being beveled outwardly on one side and inwardly on the other, an elongated discharge tube on one side of said neck and extending into the central opening in said bowl, a hood surrounding said cover and adapted to receive the lighter liquid discharged from said tube, said bowl being provided with openings in the bottom thereof through which the heavier liquid is discharged in the aforesaid receptacle, and a discharge pipe communicating with said receptacle, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
